Why is My Car Windshield Cracking?

Posted onMay 10th, 2020 byFrank

At Frank’s Auto Glass, we provide used auto glass replacement to many customers throughout the Chicagoland area. Customers see us for a variety of different kinds of repairs, including damage caused by car accidents, stones kicked up on the road, and other kinds of impacts. Sometimes, the reason for repair is simply environmental—as is the case with stress cracks.

What is a Stress Crack?

A stress crack is a straight (or slightly curved) crack that appears in your windshield due to rapid temperature changes. In order to distinguish this type of crack from another, you can test it with a dry ballpoint pen by running it along the crack. If the pen doesn’t dip, it’s likely a stress crack. It’s uncommon for stress cracks to result in any shards of glass being lost.

How Can I Avoid a Stress Crack on My Windshield?

Because stress cracks are caused by a rapid change in temperature, taking care to avoid these situations is key.

  • If you live in an area that experiences extreme temperatures—extreme heat, cold, or a combination of the two—these defects are likely to appear over several years of thermal strain. Storing your car in a temperature-controlled garage may prevent them from appearing.
  • Never use warm or hot water to try to remove ice from your car’s windows. This fluctuation in temperature can result in stress cracks. It’s best to use a scraper and cold water to remove stubborn ice.
